BRAKING DEVICE FOR RAILROAD-CARS.

Specification of Letters Patent.

Patented Sept. 30, 1919.

Application filed June 23, 1919. Serial No. 305,972.

To all whom it may concern:

Be it known that I, STANLEY ZASKEY, a citizen of the United States, andresident of North Hatfield, in the county of Hampshire and State ofMassachusetts, have invented certain new and useful Improvements inBraking Devices for Railroad- Cars, of which the following is a.specification.

This invention relates to safety stopping devices for railroad cars,tramways, and the like, and has for its'object to provide a reliable,quick acting brake that will automatically, without any attention fromthe motorman or engineer, be operated to stop the vehicle.

The above and other objects will become apparent in the descriptionbelow, in which characters of reference refer to like-named parts in thedrawings.

Referring briefly to the drawings, Figure l is a View of a car insectional elevation, the same showing my device attached.

Fig. 2 is an enlarged sectional View of the valve mechanism of the same.

Referring now in detail to the drawings, 10 represents a car on tracks11. On the underside of the end of said car are mounted a pair ofbrackets 12 supporting a shaft or pin 13. A fender 1 is pivotallymounted, as shown, on said pin. On the upper end 4 of the frame of saidfender is pivoted a rod 5, which extends into the outlet of a sandcontainer 19. A simple valve 6 is pivoted in said outlet, and the otherend of said rod 5 is pivotally attached to said valve.

The compressed air pipe 8, leading from the air chamber 13, also enterssaid outlet, as shown. The valve 6, when in its horizontal, or closed,position, shuts both the air outlet and the sand outlet, and when in itsvertical, or open, position, permits the flow of both sand and air.

Now it is apparent that, when the fender 1 strikes an object, it givesway, swinging back on its pivot 3. The upper end 4 is then swung so thatthe rod 5 pulls the valve 6 open, thus allowing sand to flow down thetube 7, and compressed air to enter so as to force the sand rapidly downthe tube upon the track. Thus, in a very short time a large amount ofsand will have piled upon the track, thus automatically stopping thecar.

By provision of my device on each end of every car of a train, acomplete sander for each track, it is evident that the train may bequickly brought to a stop to prevent serious accident such as is apt tooccur if the train is free to travel forward.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is as follows:

1. In a device of the class described, a fender pivotally mounted to theframe of a car, a sand container, a source of compressed air, a pipeconnecting said source with said container, and a valve in saidcontainer operable by said fender to permit the outflow of sand fromsaid container and of air from said source so as to force said sand fromsaid container.

2. In a device of the class described, a fender pivotally mounted to theframe of a car, a sand container, a source of compressed air, an outletfrom said container, a

pipe leading from said source into said outlet and directed toward thebottom thereof, and a valve therein operable by said fender to permitthe outflow of sand and of air so as to force said sand from saidcontainer upon the track rail.

3. In a device of the class described, a fender pivotally mounted to theframe of a car, a sand container, a source of compressed air, a pipeleading from said source to said container, a valve in said containerpivotally mounted so that when in vertical position, the outflow of boththe sand and air is prevented, and when in horizontal position, both theair and .sand are free to flow, and a link connecting said fender withsaid valve.

Signed at Northampton in the county of Hampshire and State ofMassachusetts this seventeenth day of June A. D. 1919.
